To all whom it may concern: 1

Be it known that I, WILLIAM F. DZUR, a citizenof the United States of America, and

resident of Chicago, Illinois, have invented a certain new and useful Improvement in Valve-Traps, of which the following is especi- My invention relates to traps or water seals of the kind employed largely. in connection with sinks, basins and general house plumbing, to keep sewer gas from entering the house. It has been proposed to provide and accumulations wit. in the .valve are "easily and effectively discharged therefrom.

The nature and advantages of my invention will, however, hereinafter more fully appear. p

In theaccompanying drawings, Figure 1 shows a valve-trap embodying the principles of my invention, and illustrates the ap l1cation of thesame to anordinary sink. .ig. 2 is an enlarged side elevation of the trap. Fig. 3 is a vertical section on line 3-3 in Fig. 2. Fig. 4 is a vertical sectionon line 4+4 in Fig. 3. Fig. 5 is a detail section on line 55 in Fig. .3.

The sink A can, of course, be of any suitable-known or approved character, and the ofl-take or sewer pi e B leads therefrom in the usual and wel -known manner. The trap C is-located in the said pipe, and arranged below the sink in the usual andwellknown manner. The said trap comprises a curved and U-shaped coupling or pi e portion 0. The pipe 0 leads from the sin to the said U-shaped section of the pipe. The pipe 0 leads from the said U-shaped or curved coupling or pipe section. As thus constructed, the trap is of the form ordinarily known as an S-trap, although for the broader purposes of my invention the trap may be of other well-known forms.

In the lower portion of the U-shaped pipe section 0,. a horizontal valve D is arranged and rovided with an operating handle (1. This iiorizontal valve is hollow, and provided with two relatively large openings or ways (1 and (1 adapted to register with the corresponding openings 0 and c" in the pipe coupling c. The said valve is also preferably tapered and arranged to rotate about a horizontal axis, and provided with a third opening or way 01 adapted to register with the drip ordrain opening 0 at the bot-tom ol' the said U-shaped'pipe coupling. The other end of the said valve is provided with a threaded portion (i which is preferably flattened at (Z to a correspondingly shaped hole in the washer d. The wing nut d is applied to the outer end of said threaded portions cl, and screws upon the said washer. With this arrangement. the washer and. wing nut turn or rotate when the valve is rotated.-

As shown in Fig. 4, the drip or drain opening 0 isopen, and any water or accumulations the trap can discharge therefrom through the valve-opening or way (1". If the handle be swung to the right, the opening (X will then be brought into register with the opening 0 and the drain opening or drip 0 will still be open, but the communication or conneetionwitli the sewer will be com letely shut oil. Again, should the han le be brought to a position where it points directly downward, so that it is in a position 0 posite to that shown in the drawings, a c ear passage will then'be afforded through the trap for the discharge of water from the sink, but the drip or drain opening 0 will be closed. Thus it is possible to drain from both sides of the valve, to drain from only one side thereof, and to shut oil the sewer gas and open the drain. The valve can also, of course, be used for shutting oil the sink and oening the drain. All this is accomplishe by a single three-way valve, and, furthermore, the horizontal arrangement of the valve enables it to shake up or turn over any accumulations which may form therein, thus effecting a more satisfactorydischarge of the same through the drain opening 0 With a valve-trap of this character, I find that the construction and manufacture are cheaper, and that in practice its use is more satisfactory than those heretofore employed. As the drip or drain opening discharges or drains outside of the sewer pipe, no sewer gas can enter the house through the dr in opening when the latter is open and the sewer pi e cutoff.

What claim as my: invention is:

1. In a device of the class specified, a trap or water seal provided with a general discharge passage and a drip or drain opening,

an ofl take or sewer pipe, and a rotary threeway valve controlling said passa e and openjin a second ipe'leading lnto file trap said pi e free to drain said drip'or drain opening a aptedto discharge outside of the sewer pipe and directly into the room invwhich the said device is located.-

- 2. In a device ofthe class specified, the

combination of a trap com rising a'U-shaped pipe section adapted to ho d a suitable quantity of water for efiiecting a water seal, said b e hol ow valve provided wit openings, two of said openings adapted to atrap or water seal betweenthe two pipes,-

second pipe pipe section provided with a' -general -dis-.

charge passage and a lower drip orrdrain o enin ,an off-take or sewer three lateral mainta n the. open condition of the said general discharge passage at thev same time that the third opening is, in communication with the said drip or drain opening at the bottom of the U-shaped pipe section, off-take pipe, a

said valve, and screw-threaded inean's for drawing and holding the valve in place, said valve rotatable? abopt a horizontal axis, adapted to entirely out off the off-take or sewer.pipe'-and leave the trapandj second pipe free to drain, said drip or drain open- 'ing adapted to discharge outside of-the sewer pipe and directly into the room in which the" sald device is located, substantiallyja's and for the purpose set forth.

3. In a sink-trap, a 'sinkpipe, a sewer pipe,

, .a drip or drain openin.g,'for draining the sink outside of the sewer pipe, and a single threeway valve ada ted to cut the sewer pipe oif entirely from t e sink and drain openingand leave the sink free to drain.

4. line sink-trap, the combination of a sinkpipe,'a sewer pipe, a trap or water seal between the two ipes, a drip ordrain opening, for draining t e sink outside of the sewer 'ing, for draining the sink outside of the sewer pipe, a 'rotataoutside'ol' the sewer pipe, and a single'valve eading to the trap a handle on drip or drainopening,for-drainingt e sin-k outside of thesewer pipe," and a single valve pipe, and a single rotary hollow valve "provided with three lateral'openings adapting the valve for adjustment to out the sewer pipe off entirely from thesink and drain opening and leave-the sink freeto drain.

5. In asink-trap, the combination of a sink-pipe, a sewer pipe, a trap or water seal between the two pipes,'a drip or drain openp1pe,and a single rotary valve adapted to be rotated to connect the sink pipe with .the

sewer. ipe and close theidrain opening,

'adaptec by another adjustr'nentto open the T drain and maintain communication between the twopipes, by a further rotation to entirely cut off the sewer pipeand leave the sink free to drain, and y anotheradjustment to entirely out off the, sink and open" communication between'thedrain; andthe'tt sewer ipe. 4
